DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the component mounting apparatus according to the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show the configuration of an embodiment of the present invention. 1 and 2, reference holes 2 for positioning with respect to a device (not shown) are provided near diagonal corners of a pallet body 1 formed on a substantially rectangular plate.
3 are formed. A positioning shaft (not shown) is provided at a position corresponding to the reference holes 2 and 3 on the device (not shown), and the reference holes 2 and 3 are fitted to the positioning shaft when the pallet body 1 is mounted on the device. The pallet body 1 is correctly positioned with respect to the device. On the upper surface of the pallet body 1, a pair of support portions 4 and 5 project in parallel with the short side and are integrally formed, and a first reference shaft 6 is provided between the support portions 4 and 5.
And the second reference shaft 7 are attached in parallel to the long side.

The first reference shaft 6 is movable in the axial direction with respect to the support portions 4 and 5, and is detachable. The movement of the second reference shaft 7 in the axial direction is restricted by the support portions 4 and 5. The inner diameter of a hole for holding the reference shafts 6 and 7 formed in the support portions 4 and 5 is larger than the outer diameter of the reference shafts 6 and 7. Have a certain degree of freedom.

Shutter members 8 and 9 each having a substantially L-shaped cross section are mounted on the support portions 4 and 5, respectively, and a pair of long holes 8a and 9a formed in the shutter members 8 and 9 are provided.
9a and the guide pins 10 and 11 implanted in the support portions 4 and 5, respectively, engage the shutter members 8 and
The movement range in the direction parallel to the short side of No. 9 is restricted. Further, holes 1 are provided on the outer side walls of the shutter members 8 and 9, respectively.
The shutter members 8 and 9 are formed so that the shutter members 8 and 9 can be positioned concentrically with holes formed in the support portions 4 and 5 for holding the first reference shaft 6.

On both short end sides of the pallet main body 1, two and one dampers 14 each serving as a stopper are provided, respectively. The dampers 14 are provided on the opposite side to the side on which the shutter members 8 and 9 are provided. A pair of pass / fail judgment flags 15 is attached near the short side. The flag 15 is formed substantially on a column as shown in FIG. 2, and can be moved in the axial direction by penetrating the pallet body 1 in the thickness direction. Also, a concave groove 15a is formed at two places on the outer periphery of the flag 15,
A spring 16 movably provided in the pallet body 1
The ball 17 pressed and urged outward by the pressing groove 15a
, The flag 15 is positioned and held with respect to the pallet main body 1. When the flag 15 is pressed in one of the directions of the arrows a and b by an external force, the quality of a component 18 described later attached to the pallet body 1 is displayed. Further, the shutter member 9
A rectangular opening 19 is formed between the flag and the flag 15, and an LSI card 20 as information transmission means is mounted in the opening 19.

The optical pickup 18 for a CD, which is a component, has a reference hole 21 and a reference groove 22 provided on two opposite sides in parallel with each other. And the reference hole 21 and the reference groove 2
The pickup 18 is attached to the pallet main body 1 via the reference shafts 6 and 7 by inserting the first reference shaft 6 and the second reference shaft 7 into the pallet 2 respectively.

A positioning member 23 is provided on the pallet body 1 located below the pickup 18 attached to the reference shafts 6 and 7 so that the positioning member 23 can be moved up and down. By fitting into the lower surface recess, the reference axis 6 of the pickup 18
7 is restricted in the axial direction.

Next, the operation of this embodiment will be described. First, the shutter members 8 and 9 are moved via the guide pins 10 and 11 which engage with the long holes 8a and 9a, respectively.
The holes 12, 13 formed in 9 are positioned so as to be concentric with the holes holding the first reference shaft 6 formed in the support portions 4, 5 of the pallet body 1. Next, the first reference shaft 6 is pushed out from the outside and removed from the pallet main body 1. Next, with the positioning member 23 pressed down, the reference groove 22 of the pickup 18 is fitted to the second reference shaft 7, and the pickup 1
Eight reference holes 21 are positioned so as to be concentric with the holes for holding the first reference shaft 6 formed in the support portions 4 and 5. Here, through the holes 12, 13 of the shutter members 8, 9, the first
When the reference shaft 6 is inserted, the first reference shaft 6 is also inserted into the reference hole 21 of the pickup 18. Next, both ends of the first reference shaft 6 are held by moving the shutter members 8 and 9.
Finally, the positioning member 23 is pushed up to pick up the pickup 18.
, The movement of the pickup 18 in the axial direction is locked.

Next, the pallet body 1 is attached to the apparatus through the reference holes 2 and 3. At this time, since the pickup 18 is attached to the reference shafts 6 and 7 loosely fitted to the supports 4 and 5, there is a certain degree of freedom of movement with respect to the pallet body 1. Therefore, the pallet main body 1 and the pickup 18 can be independently attached to the apparatus, and the pickup 18 can be positioned with high accuracy with respect to the apparatus regardless of the mounting accuracy of the pallet main body 1.

Next, the operation of the flag 15 and the LSI card 20 will be described. Each device determines the quality of the adjustment process or the like up to the previous process by the flag 15 provided on the pallet main body 1 after each process, and sends only the pallet to which the non-defective parts are attached to the next device. LSI card 20
For each process, recording and reproduction of adjustment and assembly information specific to a specific component are performed using a magnetic head. Accordingly, each device obtains the history information of the target component up to the previous process every time the process is performed. Each device can perform a component adjustment or assembling operation using this history information.

The parts to be adjusted or assembled have slightly different amounts of adjustment and assembly for each piece. For this reason, in performing the main operation, the apparatus moves each mechanism unit to an optimum position in advance for each target component, or performs a predicted operation by predicting a necessary operation. In the final step, data recorded on the LSI card 20 is read, and necessary data from each step can be compared with each of a good product and a defective product. At the same time, this data can be used for production control of the process.

According to the present embodiment, the adjustment and assembling operation can be performed with the minimum necessary operation using the data of the previous process recorded on the LSI card 20. In addition, since the in-process history can be recorded for each of the non-defective product and the defective product, the process management becomes easy, and the defective portion can be easily known when the defective product is reproduced.

In the above embodiment, the case where the component is the optical pickup 18 for CD has been described, but it goes without saying that the component may be another member. The structure of each part shown in the present embodiment may be changed without departing from the spirit of the present invention.

[0020]

As described above, according to the component mounting apparatus of the present invention, the pallet body is positioned on the apparatus,
Is held at a certain degree of freedom and can be freely moved , so that the data can be used for the adjustment and assembling operation of the parts with the minimum necessary operation using the data of the previous process, and the process management becomes easy. .
